The thigh prosthesis uses the latest socket manufacturing method, applying comprehensive force to adsorb the residual limb, distributing the pressure points across the entire socket. This improves upon the drawback of traditional sockets, which concentrate the pressure on a single point. By evenly distributing the force, the residual limb and socket are integrated as one, allowing patients to walk comfortably, as if with their original leg, maintaining long-term wearing comfort.
